I have a function called 'on', in a large module full of other functions. If I type '@on' in 'goto anything', I get a ton of other functions before 'on' because they happen to have an 'o' and an 'n' in their name in that order.

I'd love to be able to sometimes exactly match a symbol by its prefix, instead of randomly choosing among many options.

Maybe there's already a way to do this, in which case I'm sorry I didn't make it a Question rather than an Idea.
